Need a dependable concrete spacer for columns and beams? Ghar Plans manufactures concrete cover blocks — also called cover blocks or concrete spacer blocks — in 20mm, 25mm, 40mm, and 50mm sizes to keep rebar cages correctly centred and fully covered in RCC columns, beams, footings, and other heavy structural elements. Built from high-strength concrete, these cover blocks resist crushing under the weight of a loaded column or beam cage, protect reinforcement steel from corrosion, and keep on-site breakage to a minimum — on residential, commercial, and corporate projects across Lahore and the rest of Pakistan.
